However, I've since realised it is not a significant signal of problems to come at all. I did not prime the parting boards, but simply sprayed them with 2 pack as an after thought. Not good practice, but anyway, that's what I did. As a result, the paint has not adhered to the parting board in a convincing way. The paint on the plug itself will have much more integrity.
